1. In reproducing apparatus in combination; housing structure havingopposed walls with guide rail members carried thereby; a supply reel anda take-up reel for reproducing material; means for supporting saidreproducing material intermediate said supply reel and said take-upreel; said supporting means comprising a plurality of guide railsextending along said opposed walls intermediate thereof; a removabledrawer structure supported by said guide rails; a plurality of guiderolls supported by said drawer structure cooperating with guide rollssupported intermediate said opposed walls for guiding and supportingsaid material for movement between said supply reel and said take-upreel and corona discharge means supported by said drawer structure andmovable therewith between operative and inoperative positions. 2.Structure as specified in claim 1 wherein, said guide rails are soconstructed as to effect generally horizontal movement of said drawerstructure and vertical movement of at least the rear portion thereof foreffecting connection and disconnection of said corona discharge meansform a power connector.
 3. Structure as specified in claim 1 wherein,said guide rails are so constructed as to permit relative pivoting ofthe rear end of the drawer structure about the leading edge thereof tothereby effect generally upward movement of said corona discharge meansfor mating with a power connector.
 4. A copier comprising: a. anexternal housing; b. means in said housing including electrostaticdischarge means for forming an image on a photosensitive web as it isfed through said housing; c. a supply reel support for saidphotosensitive web mounted in said housing; d. means to feed the imagedphotosensitive web away from said image forming means; e. a removableweb guide insertable into said housing; f. support means in said housingfor said web guide so that when the free end of a new photosensitive webis taken up by said feed means insertion of said insertable web guideagainst a portion of said photosensitive web between said supply reeland said feed means causes the web to be threaded into position in saidhousing; and g. means disposed in said external housing intermediatesaid supply reel support and said feed means and cooperating with saidweb guide in its inserted position to operatively support saidphotosensitive web for movement through said copier and past said imageforming means, said last-mentioned means cooperating with said web guideupon insertion thereof to move the photosensitive web from said supplyreel support for threading thereof into said copier.
 5. A copieraccording to claim 4 in which said feed means comprises a take-up reeland a drive therefor.
 6. A copier according to claim 4 in which saidsupport means for said insertable web guide comprises at least one guiderail positioned in said housing so that said photosensitive web passesadjacent at least a portion of said image forming means when said guideis inserted.
